Where does the energy go, (approximately) inertial version. Say you are standing still and a bowler throws a cricket ball at you. It hurts! Now say you are riding a moped past the bowler and he throws the cricket ball at you. Since you are almost matching the speed of the ball it hurts a lot less. So where did the energy go? It was relative to the velocity of the victim and the bowler.
